His friend said they normally flew to the Vaal Dam and Heidelberg area for scenic flights. He took off at approximately 0543Z, and used runway 02 at Kliprivier Airfield. The aircraft was maintaining low level flight and did not climb to 6500 feet (circuit height) and maintained the crosswind heading, easterly direction, before turning south to the Vaal Dam area. A witness, who resides east of Kliprivier airfield, stated that he heard an aircraft approaching and later a loud bang. Upon inspection, he saw black smoke rising from a distance and then called the authorities to report an accident. The pilot was fatally injured and the aircraft was destroyed. It is likely that during a low level flight the pilot was forced to turn right in an attempt to avoid collision with high-tension power cables. While making a right turn, the aircraft impacted the rising terrain near the power cables. Probable Cause It is likely that during a low level flight the pilot was forced to turn the aircraft to the right in an attempt to avoid collision with high-tension power cables. While making the right turn, the aircraft crashed into the rising terrain. SRP Date 10 October 2017 Release Date 14 February 2018 CA 12-12a 01 FEBRUARY 2017 Page 1 of 1

1.12.1 The aircraft took off from runway 02 and was on its way to the Vaal Dam area. A witness, who resides on the farm east of Kliprivier Airfield, said he heard an aircraft and few seconds later a loud bang. The point of impact informs the investigators that the aircraft was flying in an easterly direction on an extended crosswind leg. The aircraft encountered two rows of high-tension power cables (height 45m or 144ft) which run north to south and tried to evade them by turning right. During a right turn the aircraft impacted the rising terrain near the power cables. 1.12.2 The aircraft nosed over and broke most of the tubular frame. The engine broke off from the aircraft and post-impact fire engulfed the aircraft. The aircraft was fitted with a BRS parachute system, but it was never used. The activating handle was still in its holder. The parachute in figure 5 was extended as a result of the rocket firing during impact sequence. All the debris was found in a radius of 10 metres. 1.13 Medical and Pathological Information 1.13.1 The post-mortem and blood toxicology reports were still outstanding at the time of compiling this report. Should any of the results have a bearing on the circumstances leading to this accident, they will be treated as new evidence that will necessitate reopening this investigation. 1.14 Fire 1.14.1 The aircraft was destroyed by impact and post impact fire. 1.15 Survival Aspects 1.15.1 The accident was considered not survivable due to the high impact forces and post impact fire that destroyed the aircraft. 1.16 Tests and Research 1.16.1 None 1.17 Organisational and Management Information 1.17.1 The maintenance records indicated that the aircraft was equipped and maintained in accordance with existing regulations and approved procedures.

ANALYSIS 2.1 The pilot was the holder of a national pilot s licence and his medical certificate was up to date. The weather was fine on the day and there were no clouds. 2.2 After making a call to his spouse, the aircraft took off at approximately 0545Z. After getting airborne from runway 02 the aircraft s flight path extended beyond the downwind leg. The witness stated that he heard an aircraft approaching and later a loud bang. The aircraft was flying low at an approximate of height of the power lines. 2.3 It is likely that the pilot turned the aircraft to the right in an effort to avoid colliding with the high tension power cables. While making the right turn, the aircraft impacted the rising terrain near the power cables. The aircraft was destroyed by impact and post impact fire 2.4 The deployment of the BRS rocket parachute had no effect on the accident as it deployed during impact. 2.5 The pilot did not deploy the BRS system as evidenced by the activation handle as it was found still in its holder. 3.
